I am a staunch nativist when it comes to wildlife. The damn English Sparrows are really bothering me this year.
We have two pestiferous Limey bird species here in Yankeeland and in the US in general - the English Sparrow (aka House Sparrow) and the Starling.
Both were imported from Albion for a variety of silly reasons, back before people realized that biological imports create a mess for native species. These were two highly aggressive, invasive species who have wreaked havoc on our gentle native birds. Now, the English Sparrow is the most widely distributed bird on earth.
Today, my irritation is with the English Sparrow. It is not, in fact, a lowly, timid mouselike sparrow at all, but probably a variety of European weaver finch. They are city birds, barn birds, and may fit into European ecology quite well but here they drive out our native sparrows and are dominating my bird feeder this year. I have no interest in feeding them because they can do very well feeding from dumpsters in parking lots and eating horse manure - one of their favorite treats.
As Beantown's Mayor Curley would have said, I'd ship them all back to England if I could.
